This checklist transcends the requirements in Part M, which simply requires “reasonable provision” to be made for access to and use of the building by disabled people, and “reasonable provision” of sanitary conveniences in the entrance storey or principal storey of the dwelling. The Approved Document goes into more detail, of course, and is set to be replaced by an even more substantial document based on BS 8300, in 2004.
